Tolkien, wary of the idea of any film adaptation of his works, sold the film, stage, and merchandise rights of The Hobbit and The Lord of the Rings to United Artists in 1968, and forbade the Disney studios, whose works he loathed, from ever getting involved in future productions. UA ended up never making a movie.
Tolkien, a devout Roman Catholic, is credited with helping to convert C.S. Lewis, a former atheist, to Christianity, but was disappointed when Lewis chose Anglicanism over Catholicism.
Tolkien was a good friend of another Oxford don who taught English literature and wrote books for children, C.S. Lewis, who wrote of him - "At my first coming into the world I had been (implicitly) warned never to trust a Papist, and at my first coming into the English Faculty (explicitly) never to trust a philologist. Tolkien was both."
J.R.R. Tolkien: The news today about Atomic bombs is so horrifying one is stunned. The utter folly of these lunatic physicists to consent to do such work for war-purposes: calmly plotting the destruction of the world! Such explosives in men's hands, while their moral and intellectual status is declining, is about as useful as giving out firearms to all inmates of a gaol and then saying that you hope 'this will ensure peace'.
